2022 Nissan Altima Transmission Problems

Your car is shutting off while you're driving and then restarting on its own, sometimes for about 5 seconds at a time. Your dashboard lights flicker every time you start the car, and occasionally the car won't start until you wiggle the battery connections. You've already tested and replaced the battery, so this appears to be an electrical system issue rather than a battery problem. The repair will likely involve diagnosing and fixing faulty electrical connections, wiring, or the vehicle's charging/electrical system components.

Your car's body control module (BCM) is not functioning properly. This component controls multiple electrical systems in your vehicle, so you may experience various electrical issues or warning lights. A technician will need to diagnose and possibly reprogram or replace the BCM to restore normal operation.
